I am a wedding photographer and mainly use lightroom 5 + photoshop cc and everyday use.

I shoot with Nikon d800 and raw files are a big pain, and my current imac is not as fast as i would like, and i have the feeling that slows me down, especially when i have 3000 picture of wedding to process.

My current setup is:

All my photos are to an external Firewire 800 HDD, and my lightroom catalogue to internal 1tb.

At option No2, i am thinking to have one ssd for operating system, one ssd for lightroom scratch, and 2 more HDD to have my photos + files. In future terms, i can upgrade up to 64 or 128gb ram... and maybe have a better graphic card...
